CLAMPING MECHANISM FOR CAN OPENERS.

' original applicatio The present invention relates to a clamping mechanism for holding the can while the same is being opened by a can opening mechanism, and the subject matter of this application, has beendivided from my pending application bearingSerial No. 61,256, filed October 8, 1925, and now issued as Patent Number 1,595,714.

The object of the invention is to provide a clamping structure of this nature which is exceedingly simple in its construction,.compact, convenient, efficient, reliable, strong, durable, easy to manipulate, not likely .to easily become out of order, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in View as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a top plan view of a machine embodying the features of my improved clamping mechanism, and

Fig. 2 is a horizontal sectional view taken therethrough, and

Fig. 8 is a vertical transverse section therethrough.

Referring to the drawing in detail, it will be seen that 5 designates a base. which may be in the form of a table top or may be supported in any other suitable manner. A can opening mechanism 6 is mounted on the base 5 and may be of any desired structure, such as is shown in my said co-pending application.

Referring in detail to the clamping mechanism for holding the can to be operated upon by any suitable can opening structure such .as is shown at 6, it will be seen that &6 denotes a substantially rectangular frame mounted on the base 5 by any suitable means, such as is clearly shown in Fig. 3, wherein is illustrated legs M. A plurality of bars 48 and 49 extend longitudinally of the frame in spaced relation to each other, the two bars 49, being centrally located and the other bars being located adjacent the sides of the frame, a pair of arcuate clamped jaws 50 having sleeves 51 slidable on bars 49 and grooved lugs 52 slidable on bars 48.

n filed October 8, 1825, Serial No. 61,256. Divided and this application filed February Serial No. 87,837.

A lever 53 is pivoted at one end as at 5 on the center of a crossbar 55 supported on the frame 46. The pivoted end of the lever 53-has a head 56 rigidly attached at a right angle thereto. Links 57 are pivoted to the respective ends of the head 56 as at 56 and to intermediate portions of the clamp jaws 50 as at 50'. These links are provided with a plurality of apertures 57 for receiving the pivotal connection between the links and the jaws so that adjustments may be made therebetween.

A rack 58 is curved and mounted at one end of the frame 46 for being engaged by the free end of the lever 53 so as to hold the said lever in different adjusted positions. It will be seen that by swinging the lever the jaws may be moved toward or away from each other, for clamping tightly or releasing said jaws from the can.

From the above detailed description, it is thought, that the construction, operation, and advantages of the invention will be clearly understood. The structure has numerous important features such as its adjustability, its compactness, and durability, and simplicity, its convenience and simplicity of operation. The structure which I have disclosed is merely given by way of example, because in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed, or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

Clamping mechanism for a machine of the class described including a rectangular frame having a cross bar, a pair of bars extending longitudinally of said frame, sleeves slidable on saidbars, curved jaws mounted on said sleeves, links pivoted to said jaws, and a head pivoted to the cross bar of said frame, there being a lever at an angle to and extending from said head, said links being pivotally engaged with said head.

In testimony whereof I afiix my signature.

STEVE A. DAVIS.
